Description
1,2-
Dimyristoyl-
sn-
glycero-
3-
PC (DMPC) is a phospholipid containing 14:0 fatty acids at the
sn-

Uses
1,2-dimyristoyl-sn-glycero-3-phosphocholine is a phospholipid containing 14:0 fatty acids at the sn-1 and sn-2 positions. It is a synthetic phosopholipid that can be used for liposome production in order to study the properties of lipid bilayer.[Cayman Chemical]
Uses
1,2-Dimyristoyl-sn-glycero-3-phosphocholine has been used as a standard for phospholipid analysis by LC-ESI-MS.
Definition
ChEBI: A 1,2-diacyl-sn-glycero-3-phosphocholine where the two phosphatidyl acyl groups are specified as tetradecanoyl (myristoyl).
General Description
Phosphatidylcholine (PC) is a strong bilayer-forming lipid. It the most common phospholipid in mammalian membranes. It is also an important component of the mucosal layer of the colon.
Biochem/physiol Actions
Phosphatidylcholine (PC) functions as a surfactant within the mucus to form a hydrophobic surface to inhibit bacterial penetrance. It is used to treat fat embolism. Phosphatidylcholine lowers the levels of cholesterol and triglycerides.
Purification Methods
It has three forms 1, 2 and '. Recrystallise it from aqueous EtOH or EtOH/Et2O. Its solubility at 22-23o in Et2O is 0.03%, in Me2CO it is 0.06% and in pyridine it is 1.3%.
